I am currently looking at buying an '87 GN, and need to know what to look for before purchasing. What should I look at mechanically? What tests should I do to confirm that the mtor is sound? Are there any markings or indicators I should look for?
Any advise would be very helpful. I am new to the Turbo Buick world.
